Research progress of T-Hg2+-T biosensor in mercury ion detection

Mercury ion(Hg2+) is a highly toxic heavy metal ion that can cause harm to people. It is important to develop rapid, sensitive and low-cost Hg2+detection methods. Methods The Chinese keywords such as "mercury ion", "THg2+-T biosensor" and "detection", as well as corresponding English keywords, were searched in various databases such as CNKI, Google Scholar and Web of Science, then the literature were sorted out. Results The application of T-Hg2+-T structure in fluorescence sensor, colorimetric sensor, electrochemical sensor and raman scattering sensor in recent 5 years are summarized. Conclusion As a Hg2+identification method, the T-Hg2+-T structure can be equipped to a series of biosensors. It has obvious advantages such as fast, sensitive and low cost, and plays an important role in the field of Hg2+ rapid detection.
